Answer:

One less than the sum of square of a number and twice the number is 0

Step-by-step explanation:

$x^2+ 2x - 1 = 0$

x represents any number. x^2 represents square of a number

2x represents twice the number

$x^2+2x$ can be written as sum of square of a number and twice the number

$x^2+2x-1$

One less than the sum of square of a number and twice the number

$x^2+2x-1=0$

One less than the sum of square of a number and twice the number is 0

How do I go about solving the problem?

Answer:

See below.

Step-by-step explanation:

You have already drawn the line x = -1 . This is the vertical line passing through the point F.

So if we reflect across this line, F will stay where it is at (-1,-1) (because F is on the 'mirror'). E is 3 units in front of the line so is reflected 3 units the other side.

The image of E, E' will be at (2, -3). The image of G, G' will be at (-2,-3).

Answer:

$\frac{11x}{3y}$

Step-by-step explanation:

$\frac{7x}{3y} + \frac{12x}{9y}$

Make both a single fraction by adding together.

$\frac{3(7x) + 1(12x)}{9y}$

$\frac{21x + 12x}{9y}$

$\frac{33x}{9y}$

Simplify

$\frac{3(11)x}{3(3y)}$

$\frac{11x}{3y}$
